Angular correlations in γγ→ρ<sup>0</sup>ρ<sup>0</sup> near threshold
, Zeitschrift für Physik C Particles and Fields, Vol: 16, Pages: 13-25, ISSN: 0170-9739We present an analysis of ρ0ρ0 production by two photons in the ρ0ρ0 invariant mass range from 1.2 to 2.0 GeV. From a study of the angular correlations in the process γγ→ρ0ρ0→π- π+π- we exclude a dominant contribution from JP=0- or 2- states. The data indicate sizeable contributions from JP=0+ for four pion masses M4π<1.7 GeV and from JP=2+ for M4π>1.7 GeV. The data are also well described by a model with isotropic production and uncorrelated isotropic decay of the ρ0,s. The cross section stays high below the nominal ρ0ρ0 threshold, i.e. M4π<1.5 GeV. The matrix element for ρ0ρ0 production is found to decrease steeply with increasing M4π. Upper limits for the couplings of the ι(1440) and Θ(1640) to γγ and ρ0ρ0 are given:Γ(ι→γγ)·B(ι→ρ 0ρ0)<1.0 keV and Γ(Θ→γγ) © 1982 Springer-Verlag.

Two-photon excitation of the tensor meson f<sup>0</sup>(1270)
, Zeitschrift für Physik C Particles and Fields, Vol: 10, Pages: 117-122, ISSN: 0170-9739We have measured charged particle pair production in two-photon scattering at the e+e- storage ring PETRA. While the main source of such events is the production of lepton pairs, the presence of an additional process is clearly indicated by the measured invariant mass distribution of the two particles and their angular distributions. We determine that the excess is mainly due to the decay f0(1270)→π+π-. We derive a width Γ(f0→γγ)=3.2±0.2±0.6 keV (statistical and systematic). © 1981 Springer-Verlag.
